Celiac disease

In today's explosion of gluten-free foods, The Food Guys hear an echo of previous food fads, like the low-fat craze of the 1980s. "It's kind of a hysteria," says Greg. Jon adds: "We all have problems with things that we eat. We all come across things all the time that cause us some discomfort. And today, the first thing that someone will suggest is "go gluten-free."

February 2nd, 2014: Jon and Greg reiterate their skepticism regarding "gluten-free" marketing by food manufacturers. In the absence of data on the prevalence of non-Celiac gluten sensitivity in the U.S., Greg observes, this condition is: "less a diagnosis than a description." Jon and Greg also discuss the evolutionary relationship between humans and gluten, particularly gliadin, one of gluten's components.
